Clinical Evaluation of OSNA Breast Cancer System to Test Sentinel Lymph Nodes From Patients With Breast Cancer

June 2, 2010 updated by: Sysmex America, Inc.

Clinical Evaluation of LS-03M/LS-04R for the Detection of Sentinel Lymph Node Metastasis From Breast Cancer

The study will determine the sensitivity, specificity, negative predictive value and positive predictive value of the OSNA Breast Cancer System by comparing its performance to permanent section Hematoxylin and Eosin (H&E) and IHC staining.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Patients with a previous diagnosis of breast cancer scheduled for sentinel lymph node dissection.

Description

Inclusion Criteria:

  • Male or Female patients, over the age of 18, diagnosed pre-surgically with T1 or T2 breast cancer and scheduled for surgery including sentinel node dissection.
  • Patients who have read and understand the informed consent form and are capable and willing to provide written informed consent.

Exclusion Criteria:

  • Patients diagnosed pre-surgically with large or locally advanced (T3 and T4) breast cancers.
  • Patients diagnosed with inflammatory breast cancer.
  • Patients diagnosed with ductal carcinoma in situ (DCIS) when breast conserving is to be done.
  • Patients who are pregnant, as confirmed by a patient/treating physician interview.
  • Patients with suspicious palpable axillary lymph nodes.
  • Patients currently being treated for or previously diagnosed with, another type of carcinoma.
  • Patients who have undergone prior non-oncologic breast surgery or axillary surgery.
  • Patients who have received pre-operative systemic therapy.
  • Patients who are incapable of providing written informed consent.
  • Patients who have been judged to be inappropriate by a medical care provider (i.e. surgeon, oncologist, pathologists, etc.).

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
OSNA Breast Cancer System
Device: OSNA Breast Cancer System

For in vitro diagnostic use only.

The OSNA Breast Cancer System is an automated semi-quantitative, in vitro diagnostic test for the rapid detection of greater than (>) 0.2 mm metastases in nodal tissue removed from sentinel lymph node biopsies of breast cancer patients. Results from the assay can be used to guide the intra-operative or post-operative decision to remove additional lymph nodes and to aid in patient staging. An assay positive + or ++ result indicates the presence of metastasis (> 0.2 mm). An assay positive ++ result predicts the presence of macrometastasis (> 2 mm).

Post-operative histological evaluation of permanent sections of the tissue specimen, in accordance with usual diagnostic practice and using the Sysmex lymph node cutting scheme, is required.

What is the study measuring?

Primary Outcome Measures

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
February 1, 2007

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
